QX90 prop guard - reinforced joints - 2.1 grams

Prop Guard for QX90 Micro Quadcopter Propeller Protection System Designed to fit the QX90, but also compatible with other quadcopters of similar dimensions. Printed in high-quality ABS material with a 100% infill density, this prop guard tips the scales at just 2.1 grams. After researching alternative designs, I found them to be impressive, but unfortunately prone to breaking at the 90-degree joints or adding excessive weight. To address these issues, I've rounded off the joints in my design, aiming to increase their strength and durability. I've also opted for a single arm per motor configuration, which should provide a more flexible prop guard that bends before breaking. If you decide to give this prop guard a try, please let me know how it performs.
